Are you often somniloquy?

Hi my friend,I want to know are you often somniloquy?
My roommate said they often hear my words when i was sleeping this days,it is terrible,I don't know why?
But you are hard to answer it,maybe you do not know wether you are somniloquy or not,because when you do that,you do not know like me.lol.what should I do?
